Spinal decompression is a type of therapy that stretches the spine in order to relieve back or leg pain. Non-surgical spinal decompression therapy uses a traction table or similar device to achieve optimal results.
Doctors have used nonsurgical spinal decompression in an attempt to treat:
- Back or neck pain or sciatica, which is pain, weakness, or tingling that extends down the leg
- Bulging or herniated disks or degenerative disk disease
- Worn spinal joints (called posterior facet syndrome)
- Injured or diseased spinal nerve roots
